One of the things that worked in TNG's favor was that they didn't try to shoehorn new characters into the roles of the old characters. So that "new Spock" is a pretty bad take from someone really oversimplifying things.
The only time they really failed in this regard was in season 2 where they tried to create an antagonistic relationship between the doctor and Data, a la McCoy & Spock. But while Spock was a sarcastic asshole who gave as good as he got, Data was so childlike and vulnerable that every Pulaski jab felt like she was cruelly punching down at someone incapable of defending himself.
